Description

Beschleunigungs- und Verzögerungsmesser, insbesondere für Kraftfahrzeuge Die Erfindung betrifft einen Beschleumgungs- und Verzögerungsmesser, insbesondere für Fahrzeuge, wie Kraftfahrzeuge o. dgl. Bei derartigen Geräten ist es bekannt, zur Anzeige eine Kugel zu verwenden, die in einem zur Waagerechten geneigten Rohr, dessen Neigung an einer Skala einstellbar ist, frei beweglich ist. Es ist ferner blekannt, den Rahmen des Gerätes um eine quer zur Fahrtrichtung liegende Achse an einer zur Befestigung des Gerätes am Fahrzeug dienenden Platte 0. dgl. anzulenken und dabei feststellbar zu machen.Accelerometers and decelerometers, in particular for motor vehicles The invention relates to an acceleration and deceleration meter, in particular for vehicles, such as motor vehicles or the like. In such devices, it is known to use a ball for display, which is in a tube inclined to the horizontal, whose inclination is adjustable on a scale, is freely movable. It is further bled, the frame of the device around an axis lying transversely to the direction of travel a plate used to attach the device to the vehicle 0. Like. To articulate and to make it detectable.

Die Erfindung besteht darin, daß das die Kugel enthaltende Rohr am Geräterahmen in seiner Mitte um eine quer zur Fahrtrichtung angeordnete Achse drehbar und in verschiedenen Schrägstellungen feststellbar gelagert ist. The invention consists in that the tube containing the ball on Device frame rotatable in its center around an axis arranged transversely to the direction of travel and is mounted lockable in different inclinations.

Das Gerät nach der Erfindung hat vor den bekannten Geräten den Vorteil, daß es bei unveränderter Anbringung am Fahrzeug in sehr einfacher und bequemer Weise sowohl zur Anzeige der Verzögerungen als auch der Beschleunigungen verwendet werden kann. The device according to the invention has the advantage over the known devices that it is very easy and convenient to do with unchanged attachment to the vehicle can be used to display both decelerations and accelerations can.

Dies wird durch einfaches Umstellen des die Kugel enthaltenden Rohres erreicht Für die Messung von Verzögerungen wird das vordere Ende des Rohres nach oben gerichtet, während es für die Messung von B,eschleunigungen nach unten geneigt ist.This is done by simply moving the tube containing the ball For the measurement of delays, the front end of the tube is reached directed upwards, while it is inclined downwards for the measurement of B, accelerations is.

Ein Ausführungsbeispiel des Gerätes nach der Erfindung ist in der Zeichnung in Seitenansicht dargestellt. An embodiment of the device according to the invention is in Drawing shown in side view.

Das Glasröhrchen I, in dem sich die Stahlkugel 2 bewegt, ist um den Zapfen 3 drehbar angeordnet und kann durch eine durch den Schlitz 6 greifende Klemmschraube 4 vor den Skalen 5, 5' in jeder Stellung festgestellt werden. The glass tube I, in which the steel ball 2 moves, is around the Pin 3 is rotatably arranged and can by a clamping screw reaching through the slot 6 4 can be determined in front of the scales 5, 5 'in every position.

Vor Beginn der Bremsprüfung wird das Gerät mit seiner Platte 7 durch Schrauben. Before the start of the brake test, the device with its plate 7 is through Screws.

Gummisaugnäpfe 0. dgl. an einer Wand des E>ahrzeuges so angebracht, daß Fahrzeuglängsachse und Glasröhrchenlängsachse in gleicher Richtung verlaufen. Dann wird das um den Zapfen 8 schwenkbare Gerät nach der Wasserwaage g eingestellt und durch die in den Schlitz 13 eingreifende Klemmschraube 10 an dem bei ii an der Platte 7 angelenkten Arm 12 in dieser Lage festgestellt.Rubber suction cups 0. The like attached to a wall of the vehicle in such a way that that the longitudinal axis of the vehicle and the longitudinal axis of the glass tube run in the same direction. Then the device, which can be pivoted about the pin 8, is adjusted according to the spirit level g and by engaging in the slot 13 clamping screw 10 on the at ii on the Plate 7 articulated arm 12 found in this position.

Die Einstellung des Röhrchens I erfolgt so, daß das, in Fahrtrichtung gesehen vordere Ende höher liegt als das hintere Ende, wobei die Neigung entsprechend den zu prüfenden Bremsverzögerungswerten gewählt wird. The setting of the tube I is done so that that, in the direction of travel seen the front end is higher than the rear end, the inclination accordingly the braking deceleration values to be tested is selected.

Durch einfache Verschwenkung des Rohres in die entgegengesetzte Schrägstellung kann das Gerät auch als Beschleunigungsmesser verwendet werden, ohne daß man es von der Fahrzeug'wand, an der es befestigt ist, zu lösen braucht. By simply swiveling the tube into the opposite inclination The device can also be used as an accelerometer without having to use it from the vehicle wall to which it is attached.

Wenn das Gerät nur dazu dienen soll. eine oder mehrere mittlere Bremsverzögerungen zu prüfen, z.B. die heute vorgeschriebene Verzögerung von 2,5 m/Sek. für die Fußbremse und 1,5 mISek. für die Handbremse, so genügt es, auf der Skala 5 nur zwei diesen Verzögerungen entsprechende Einstellmarken vorzusehen. Das Erscheinen der Kugel über der unteren Abdeckung des Rohres 1 zeigt dann die Ordnungsmäßigkeit der Bremse an. Bleibt die Kugel. während des Bremsvorganges oberhalb der Abdeckung, so ist dies eine Anzeige dafür, daß der Bremswert in jenem Augenblick den vorgeschriebienen Mindestwert nicht unterschritten hat. If the device is only intended to serve this purpose. one or more medium braking decelerations to be checked, e.g. the currently prescribed deceleration of 2.5 m / sec. for the foot brake and 1.5 msec. for the handbrake, it is sufficient to only use two of these on scale 5 Provide appropriate setting marks for delays. The appearance of the ball above the lower cover of the tube 1 then shows the correctness of the brake at. The ball remains. during the braking process above the cover, so is this is an indication that the braking value was prescribed at that moment Has not fallen below the minimum value.
